OpenRail Overhead Line Designer introduces a new, comprehensive modeling environment for rail overhead line and track design. Developed jointly by Bentley Systems and Siemens Mobility, it combines OpenRail Designer technology with Sicat Master. The application brings 3D to the world of overhead line catenary systems, advancing workflows beyond traditional plan production into the development of digital twins with asset information for the entire lifecycle. Implementation of digital twin technology will significantly decrease production time of construction deliverables, including plan layouts, reports and detailed structural erection diagrams.
